Different to vs. different from/than

Can any Brit or Anglophile explain why you people say "different to" and not "different from" or "different than"? Do you never say either or the latter, or is "different to" only for some cases? Cheers!

'We people' do not use 'different to'

Or possibly I should say that I personally do not use it, though you will no doubt have heard it used by many others in the British media. My own view is that the correct form is 'different from'. Consider the sentence ' This item differs from that item' which could also be written as 'This item is different from that item'. I don't believe that anyone would say 'This item differs to that item', and consequently I don't believe that 'to' is correct in the second form either. However, English has changed over the years, and many changes have resulted from incorrect usage, which has subsequently become accepted simply because it is so common, and this would appear to be the case with 'different to'. The infrequency of use of this form in the USA is probably explained by divergence of the two languages over 3 or 4 centuries.

Re: Different to vs. different from/than

"Different from" is the construction that no one will object to.
"Different to" is fairly common informally in the U.K., but rare in
the U.S. "Different than" is sometimes used to avoid the cumbersome
"different from that which", etc. (e.g., "a very different Pamela
than I used to leave all company and pleasure for" -- Samuel
Richardson). Some U.S. speakers use "different than" exclusively.
Some people have insisted on "different from" on the grounds that
"from" is required after "to differ". But Fowler points out that
there are many other adjectives that do not conform to the
construction of their parent verbs (e.g., "accords with", but
"according to"; "derogates from", but "derogatory to").

The Collins Cobuild Bank of English shows choice of preposition
after "different" to be distributed as follows:

"from"

U.K. writing 87.6
U.K. speech 68.8
U.S. writing 92.7
U.S. speech 69.3

"to"

U.K. writing 10.8
U.K. speech 27.3
U.S. writing 0.3
U.S. speech 0.6

"than"

U.K. writing 1.5
U.K. speech 3.9
U.S. writing 7.0
U.S. speech 30.1

However, Google search results tell that the order of usage is the following:

1. Different from: The most used.
2. Different than: The second most used.
3. Different to: The third most used.
